Abstract

L'invention concerne un système, un procédé et un support lisible par ordinateur permettant de quantifier des données de pas de données audio. Le procédé comporte les étapes consistant à : saisir des données audio représentant une trame numérotée d'une pluralité de trames numérotées ; calculer une classe de trame, la classe étant soit voisée, soit non voisée ; calculer, si la trame est de classe voisée, un pas de la trame ; calculer, si la trame est une trame numérotée paire de classe voisée, un mot code d'une première longueur par la quantification absolue du pas de trame ; calculer, si la trame est une trame numérotée impaire de classe voisée et qu'une trame fiable est disponible, un mot code d'une deuxième longueur par la quantification différentielle du pas de trame ; calculer, si aucune trame fiable n'est disponible, un mot code présentant la deuxième longueur par la quantification absolue du pas de trame.
